I was amazed to see part of the number plate in the rear camera view a few months ago. I've had my ZS EV Mark 1 for 3 years now, and hadn't noticed that before. My first reaction was wow, what happened, but then I came to think that it was there all along and I never noticed it.
For what it's worth, my view of the number plate is about half, perhaps a smidge less, of what is in that photo.
It seems unproductive to have that area wasted. Maybe you and I have a problem of alignment, and yours is about twice as far off as mine is. I suppose the most important thing is whether the coloured lines are accurate or not. I'd hate to move the camera, and get 10% more "useful" view, only to find that the coloured lines are now useless. I think
@Rolfe has mentioned that she knows where the back of her car is to the centimetre (or was it some fraction of an inch).
Anyone else care to comment, even if it's to say "what numberplate?".
